of convenient size is directed upwardly so that a person lacing his mouth over the fountain may rink'from the jet without touching the nozzle. Fountains of this t e are now more or less generally inuse inpubiic places, such as parks, school buildings, and public highways. But hitherto such fountains have been provided with but a single outlet so that a person placing a finger over the outlet maycause thestream of water to s urt laterally with relatively great velocity,

epending upon the pressure-of the water. The practice 'of misusing. these fountains in this way is extensive, especially in the school buildin ex use to mischievous persons.

The desired result is 'obtainedby lpro .viding a sup lemental outlet in addition to the usual out et, the su plemental outlet bein arran ed to directt e water downwardly wliem'an' only when, the main outlet. is obstructed. The so. plemental outlet is so formed as to be di cially the hand,and the aforesaid misuse.

cult of obstruction, espea chamber formed by casing 11, having a cap or cover 12. Water is delivered into the chamber 10 under pressure to be discharged therefrom through a main outlet 13, opening upwardly and formed by an inwardly projecting annular flange on the cap, said flange being imperforate as shown. The

.jet of water which escapes through the outlet 13 is intendedfor drinkin and it rises vertically'toa-short distance a ove the cover 12. As here shown,"water under pressure is conducted to the casing 11 by a service pipe 14, from which the water flows into the lower part. of the casing through the inlet 15. The water, which enters the lower part of the casing, may pass into the chamber 10 through a nozzle formed by a port 16 extending through a central stem formed on a Patented Oct. 2.5, 1910.

piston '17. The piston divides the s ace in the casing into two cha'mbers,'name y, the chamber '10 previously mentioned and the chamber 18. The piston is subject to the tension of a spring 19 which tends to move thepiston toward the inlet 15. The piston is'provided with a pressure-regulating valve 20 which controls the. inlet 15 so as to admit a uniform quantity of water however the pressure in the service pipe 14: may vary.. I

he capacity of the portlG is less than that of the inlet 15, and consequently the chamber 18 becomes a pressure chamber when water is forced'throu'ghthe inlet 15. When the volume of water admitted by-the inlet 15 is fipeater than that which may. escape throu h e'port '16, pressure .is developed in t e chamber 18 forcing the piston upwardly,

The valve '20 is thus caused to obstruct the f inlet 15 toafgreater-extent, thus. maintaining a uniform 18., In this way, the piston and valve automatically compensate for/variationsof the pressure in the servicepipe, the result .being that a uniform volume of water is discharged through the main outlet 13. -The re'gu at-ing means just referred to forms the subject-matter of my cO-pending applica tion, Serial No. 539,965, filed January25,'

which is also flared as indicated at water, which is thus introduced into the out let 13, loses a greater proportion of its force and it bubbles very gently above the cap 12 in a jet which is convenient for drinking.

The chamber 10 is providedwith one or more supplemental outlets through which the water does not normally pass, but pass when the main y In the form shown by 1 and 2, the supplemental outlets for the chamber 10 are formed in the cover 12 which forms a part of the'casing 11. These outlets are shown-in the form of portsindicated at 21. Theouter ends of the ports 21 are covered by'an annular flange 22 which I rt's and extends down- When the main outlet 13 is obstructed, the; water issuin from the port '16, fills the chamber 10" an overflows through the supplemental outlets 21. It is deflected by] the downwardly extending flange 22 so t at it is caused to run down the exterior of the casing 11. The

' j level of the water in the chamber stands normally below said outlets and above the lower endof'the e surrounding the port 13, whereby air is not drawn through said port 13 with the jet or bubble delivered therethrough bythe nozzle 16. Thecasing is from the nozz supplemental ingflange'22, whose functionis- *form, like thatof Figs. land 2, the

The form i ustrated by Fig. 3 is like. that Figs. 1 and 2, with the-exception the flange sur- 3, the cha'mber'lO isnotfla' pressure 'cham r because the area of the nozzle 23 is less than the outlets.

This form is provided withoutlets 21 and the overhan recisely t, e same as'in the form first descri ed.
